Questions
Where can I sell my diamond near me?
At Royal Gold Buyers in Rockville Centre (29A N Village Ave) or Garden City (671 Franklin Ave). Walk in Monday to Saturday, 10 AM to 6 PM. A certified gemologist evaluates your diamond in front of you and you are paid the same day.
Do I need a GIA certificate to sell my diamond?
No. We buy diamonds with or without a GIA or other lab certificate. A certificate is welcome, but our certified gemologist evaluates every diamond in front of you either way.
How do you decide what my diamond is worth?
We look at the 4Cs – carat weight, color, clarity and cut – plus the gold or platinum in the setting, then base the offer on current diamond market prices. Every offer is explained clearly.
Can I sell my engagement ring after a divorce?
Yes. Many of our customers do. The process is quick, private and respectful, and there is no obligation to sell after the free evaluation.
Do you buy diamond earrings, bracelets and necklaces?
Yes. We buy diamond studs and earrings, tennis bracelets, tennis necklaces, pendants, chains, anniversary bands and designer diamond jewelry such as Cartier and Tiffany.
How do I get paid?
Cash or a same-day bank wire, on the spot.
What do I need to bring?
Your diamond or jewelry and a valid photo ID, such as a driver’s license, state ID or passport. We need a photo ID for every sale.
Do I need an appointment?
No. Walk in to either store Monday to Saturday, 10 AM to 6 PM, or text us a photo first for a quick quote. For large estates we also offer free house calls in Nassau County.
